Okitsu scuttled away on all fours. “I can’t!” she cried. “I promised Koheiji I wouldn’t tell.”
“That you lie to the shogun’s detective for Koheiji shows what a fool you are,” Agemaki said with withering disdain. “He doesn’t love you. He’ll never marry you. He’s just leading you on so you’ll protect him.”
“You’re wrong! He does love me! We are getting married!” Okitsu reared back on her heels as she shouted at Agemaki.
“I caught him making love to a woman in his dressing room at the theater,” Hirata said.
“No! He didn’t! He wouldn’t!” But the quaver in Okitsu’s voice belied her defiant words.
“Koheiji is due to take the punishment for Senior Elder Makino’s murder,” Sano said. “Unless you want to share it with him, you’d better start talking.”
For a moment Okitsu sat silent, her face bunched into a pout. Then she wilted under the knowledge that her friends had betrayed her and she was on her own. She uttered a querulous sob.
“You and Koheiji performed for Makino that night…” Sano prompted.
Okitsu nodded. “We did our usual routine,” she said in a weary, toneless mumble. “I gave Makino some cornus berry tea.” This was a potent aphrodisiac. “Then he watched Koheiji and me while we undressed and started making love. Pretty soon he joined in with us.”
Sano imagined Makino eagerly sipping the aphrodisiac, watching the amorous couple, then the grotesque entwining of sleek young bodies and the wrinkled, emaciated one.
“But Makino couldn’t get excited,” Okitsu said. “No matter what we did, he stayed limp as a dead worm. Koheiji even tried playing rough. He tore my clothes off me and tied my wrists and pretended to hit me. That usually got Makino going, but this time it didn’t. He asked for more cornus berry tea. I gave it to him. We started the game again. I sucked on Makino while Koheiji took me from behind.”
She spoke without shame, as if discussing the weather. Sano recognized the scene Agemaki had told him she’d witnessed while spying on the trio.
“Pretty soon, Makino was as hard as iron,” Okitsu continued. “He said he was ready. Koheiji lay down on the bed. I got on top of him and took him into me. Makino stuck himself in my backside.” Okitsu leaned forward, knees apart, balancing on her hands, and unconsciously pantomimed the mating. “Makino went wild. He was moaning and ramming me so hard and fast that it hurt. All of a sudden, he made a sound like he was choking. Then he fell on top of me.” Okitsu dropped flat on the floor, her voice and expression conveying the surprise she must have felt when crushed between her two partners. “Koheiji said, ‘What happened?’ We pushed Makino off us. He flopped onto the bed. We sat up and looked at him.”
Okitsu suited action to words. Sano pictured Koheiji beside her, both of them gazing in puzzlement upon their inert master. “He didn’t move,” Okitsu said. “There was spit oozing out of his mouth. His eyes were open, but they had a sort of empty look. Koheiji called his name, but he didn’t answer. I shook him, but nothing happened. Koheiji said, ‘He’s dead.’ ”
Sano heard in her voice the echo of Koheiji’s, replete with horror. Amazement filled Sano. If she was telling the truth-and he thought she was this time-then this death he’d been investigating wasn’t a murder. Makino hadn’t died by foul play, a victim of his enemies, as his letter had claimed. Nor had Daiemon hired Koheiji to kill him. Someone had planted the note in Daiemon’s secret quarters and the story at the Floating Teahouse to make Daiemon appear responsible for Makino’s death. And Sano could guess who. Chamberlain Yanagisawa, with all his spies, must have discovered the secret quarters. The scheme to incriminate his enemy fit his devious nature. He must have expected Sano to find the false evidence during the course of the investigation. Sano was certain that if he hadn’t, Yanagisawa would have devised an alternate plan for bringing the note to light. But Yanagisawa couldn’t have known that his false evidence would lead Sano to the truth.
“I thought Makino had died because he’d strained himself too hard,” Okitsu said. “Koheiji said it was the extra cornus berry tea.”
Or perhaps his death had resulted from a convulsion due to both aphrodisiac poisoning and strenuous sex, Sano conjectured.
“But we didn’t kill him,” Okitsu said, hysterical with her need to convince. “We didn’t mean to hurt him. It was an accident!”
Relief showed on Otani’s face, and chagrin on Ibe’s. Hirata looked disappointed. Agemaki beheld Okitsu with loathing, obviously upset that her husband’s death wasn’t her rival’s fault. Sano shook his head. That the investigation should turn out like this! He’d crossed Lord Matsudaira and Chamberlain Yanagisawa, and risked his wife and son’s safety, all because Senior Elder Makino had succumbed to his own lust. Yet the investigation wasn’t over. A gap in the story divided the moment of Makino’s demise and the instant when Agemaki had found his corpse in the study.
“What happened after you discovered that Makino was dead?” Sano asked Okitsu.
“I told Koheiji that we should get help, we should tell someone,” Okitsu said. “But Koheiji said, ‘No! We can’t!’ " She grabbed her arm, as he must have done. “He said there was nothing anyone could do to save Makino. He said people might blame us for Makino dying. We could be put to death.” Her eyes grew round with the fear Koheiji had instilled in her. “I said, ‘What shall we do?’ Koheiji said he had an idea. He told me to get dressed fast. The sleeve of my kimono had gotten torn off during our game, and he wiped himself on it before he put on his clothes.”
Sano saw the actor carelessly tossing aside the sleeve, which would later turn up in Makino’s bedding.
“Then he told me to help him dress Makino.” Okitsu shivered and grimaced. “It was weird, like dressing a big doll. Afterward, we moved him to the study. You wouldn’t think a skinny old man like him could be so heavy, but it took both of us to carry him. We laid him on the floor. Koheiji broke the window latch. He said that would look as if someone had sneaked into the house and killed Makino. Then he ran outside and trampled the bushes.”
That explained who had planted the signs of an intruder and why, Sano noted.
“When he came back, he brought a wooden pole,” Okitsu said. “He told me to mess up the room. While I was throwing papers and books around"-Okitsu winced-“Koheiji was hitting Makino with the pole, to make it look like he’d been beaten to death.”
Sano wondered if, when Makino had written his letter, he had considered the possibility that his death would result from a natural or accidental cause rather than assassination. Probably he had. Makino had been an opportunist who must have viewed his own inevitable death as a final opportunity to exploit, a last chance to make trouble for the enemies he left behind. A murder investigation by Sano would have suited his purpose. He’d have relished the thought of his enemies harassed and persecuted as suspects, even if nobody was ever punished for his death because it turned out not to be a murder. He couldn’t have known that his death would involve his sexual games and the suspects would include his two partners.
“Koheiji hit Makino’s head. It bled all over the floor,” Okitsu said.
Her words reminded Sano of what he’d learned while examining corpses with Dr. Ito at Edo Morgue. He also remembered the bruises they’d found on Makino’s corpse. His idea of what had happened to Makino, which had changed time after time throughout his inquiries, suddenly shifted again.
“Koheiji put out the lanterns in Makino’s chambers,” Okitsu said. “He took me to his room. He said we should stay there until morning, and if anyone asked, we should say we’d been together the whole night and we hadn’t been near Makino at all. I said, ‘What if Agemaki heard us? She’ll know we’re lying.’ ”
